ABSTRACT:
A method and apparatus for regulating the anode current of a gas lasing system with reduced power dissipation is disclosed. According to this invention a feedback loop is connected between the anode circuitry and the high voltage power supply such that the anode current regulator has a much lower voltage across itself than has been the case in the past. Since the voltage across the current regulator is reduced, there is not nearly as much power for the regulator to dissipate. In addition, because of the smaller power handling requirements, a stabilized anode current can be achieved at about half the level required by prior art circuitry. Thus, the power dissipation can be reduced even further.
